Earned Schedule, since it was introduced by Walt Lipke in 2003, has been studied extensively in a variety of different fields and on programs of all sizes. However, Earned Schedules viability as an extension of Earned Value Management EVM in Major Defense Acquisition Programs MDAP has yet to be effectively answered. The first aspect of this research explores the breadth of Earned Schedules adoption by the System Program Offices SPO of the United States Air Force. The second phase of this research explores whether Earned Schedule is a more accurate and timely schedule predictor than the EVM technique currently employed by the United States Department of Defense DoD. A series of five descriptive statistical tests were conducted on the Earned Value data for 64 Acquisition Category ACAT I MDAPs. This research finds Earned Schedule to be a more timely and accurate predictor than Earned Value Management.
